It's a billet wheel, I'd give Wade over at ATS Diesel a call. I personally would run the shit out of it. But then again, it's not a good idea to have different loads from one fin to another, would think it would cause some flexing. But, you may be able to send the turbo center section to them and have the problem corrected at a low cost to you. Or just try and straighten it yourself. Just match the curve of the other fins. To do this, take the compressor housing off and use cloth and pliers to work the fin. Be careful not to bend the lower part of the fin.
What caused the bend, and is the shaft straight? Was the fin bent with the compressor housing off? And is there a nick in the fin?
